STL → USDZ: what you should know
STL is the standard format of 3D printing: a triangle mesh with no explicit units, no color and no materials. It's used mostly in slicers (Cura, PrusaSlicer, Bambu Studio), FDM and resin 3D printing, CAD, and it stores geometry only (triangles and normals). USDZ, on the other hand, is Apple's augmented-reality format, based on Pixar's Universal Scene Description — the format expected by AR on iPhone/iPad (Quick Look), product pages with view-in-your-space, iOS/visionOS.
This tool converts your STL files to USDZ right in the browser: no queue, no artificial size limit and, above all, your file is never uploaded to any server. Geometry is preserved with the exact coordinates and scale of the original — important if the model is going to be printed or measured.
Converting STL to USDZ loses nothing that matters: what goes in is what comes out, in the format you need.
